The formal launch will occur at SeeTheLight.com on Friday. If you're feeling lucky, however, you might try setting your system clock to Saturday or later; earlier in the week, doing so unlocked the launch site itself, which previously redirected to vepexp.microsoft.com. That site seems to have disappeared at post time, however.

According to a press PDF posted to the site, however, Silverlight 3 will support Full HD (1080p) video, deep zooming, "smooth streaming" (or streaming with little to no buffering) and out-of-browser support, for download-to-rent applications. Silverlight 3 is based on XAML, which is also used by both Expression Studio and Visual Studio, according to Microsoft.
